Dr. Helvetica:
If i think about it, shouldn't this Magic Square be a lifeless organism even if it may be the symbol of that Purified Ceremony Hall? I think one can destroy something like this to be a spy.
But if you're really a spy from the Purified Ceremony Hall, you won't be able to destroy the Guardian Spirit of the Magic Square and Evil Spirit close in the Magic Square, which are almost like their companions. Thus, I won't be able to doubt you anymore if you can destroy those and bring 20 broken fragments of the Guardian Spirit.
Thus, please hurry and leave for the Purified Ceremony Hall!
